Referring to Fig. 2 and Fig. 3, the aerator 6 of flotation column generally distributes along single even circumferential on flotation column body wall face 7 at present, and external air is filled with in the flotation column by it after feeding aerator 6.
Mainly produce two drawbacks when adopting conventional aerator configuration mode inflation.At first, the uniformity coefficient that gas in the aerator disperses in flotation column can be subject to the impact of flotation column cross section size, the little then gas dispersion of cross-sectional area degree is higher, be easy to control, cross section is large, and the gas that then sprays because of the aerator nozzle is limited in scope and causes gas can't be dispersed on the whole cross section of cylinder; Secondly, it is high that the flotation cylinder is generally 8～15m, should guarantee certain mechanical strength on the cylinder direction, and aerator is too much in the quantity that the single circumferencial direction of cylinder wall distributes, and overstockedly then can affect the intensity on the flotation column wall circumference and be difficult to maintenance and inspection.Gas dispersion degree direct influence apparatus and process performance in the flotation column, guarantee from aerator be filled with gas in the flotation column can be on the cylinder cross section Uniform Dispersion, make simultaneously the flotation column cylinder have enough mechanical strengths and aerator repair and maintenance condition easily, this aerator configuration mode obviously has limitation.
Summary of the invention
Purpose of the present invention is exactly the problem that exists for prior art, a kind of flotation column is provided, this flotation column is optimized the distribution spatially of flotation column aerator, make the installation quantity of aerator can not be subject to the restriction of flotation column cross section size, under the prerequisite that guarantees flotation column cylinder mechanical strength, realize better the even distribution of air in flotation column.
Above-mentioned purpose realizes by following proposal:
A kind of flotation column, it comprises the shower water assembly, gives ore deposit system, cylinder assembly and Tailings System, it is characterized in that, described flotation column also comprises at the bottom of the flotation column tapered pole and a plurality of flotation column aerator, be positioned at the bottom of described flotation column at the bottom of the described flotation column tapered pole, on described a plurality of flotation column aerators are installed at the bottom of the described tapered pole.

The specific embodiment
Flotation column of the present invention comprises the shower water assembly, gives ore deposit system, cylinder assembly and Tailings System, and, flotation column also comprises at the bottom of the flotation column tapered pole and a plurality of flotation column aerator (referring to Fig. 4), 8 bottoms that are positioned at flotation column at the bottom of the flotation column tapered pole, be infundibulate at the bottom of the flotation column tapered pole at the bottom of 8 the cone downwards, the inwall welding of top edge and cylinder assembly.8 are the flotation column aerator configuration position that provides an ample space at the bottom of the flotation column tapered pole, guarantee aerator can the differing heights position in this space on many circle distribution; And can promote that ore pulp is discharged smoothly in the flotation column, prevent mineral grain accumulation sinking.
On a plurality of flotation column aerators 7 are installed at the bottom of the tapered pole, as shown in Figure 4, a plurality of flotation column aerators 6 are vertically mounted on the differing heights position at the bottom of the described flotation column tapered pole, and the many circle distribution at the bottom of the described flotation column tapered pole, in the embodiment shown in fig. 6, flotation column aerator 6 is equally distributed.
Referring to Fig. 5, distributing is set with wear-resistant steel pipe 9 in the end of a plurality of flotation column aerators 6 (among the embodiment shown in Figure 5, wear-resistant steel pipe 9 is sleeved on the part at the bottom of flotation column aerator 7 protrudes tapered pole).The turbulent flow that produces when wear-resistant steel pipe effectively avoids high speed and high pressure gas to mix with ore pulp and the ore pulp that flows out fast from the cylinder conical lower portion prevent the aerator wearing and tearing to the percussion that inflator end causes.
During use, spray in the flotation column at a high speed by aerator and under the effect of aerator nozzle from the gases at high pressure of air compressor machine, mix with ore pulp in the flotation column.Aerator in many circle distribution on the differing heights position of flotation column conical lower portion has overcome traditional flotation column aerator drawback that distributions produces on the single circumference of flotation column cylinder wall, the gas dispersion degree that is filled with in the flotation column is obviously improved, be not subjected to the impact of flotation column cross section size.The wear-resistant steel pipe that is welded in advance the flotation column conical lower portion has effectively slowed down the turbulent flow that produces when high speed and high pressure gas mixes with ore pulp and the percussion that inflator end is caused from the quick ore pulp that flows out in cylinder bottom, prolong the service life of flotation column aerator, strengthened the stability of equipment.
